Keep in mind that the clock stops for you LSAC GPA as soon as you earn a bachelors degree.
So if you have taken another course at a junior college and received a grade before graduation then you are on the books with a grade, otherwise I suspect that you are going to be considered without a grade. Even if this is the case, I would not worry much, first off, most schools seem to weigh the LSAT more heavily than the GPA anyway, secondly, foreign students are considered as having no GPA according to the LSAC, and many such students enter into US law schools all over the spectrum, so being without a GPA will not confuse an admission committee, they will simply move on to other indicators in your application.
